Although not a Prime distributor the Inverter was received quickly (less than five days from order), well packaged and all accessories noted were included (the extra long LP hose is a benefit). Ran a 3 hour break in including bring the load to 50% of capacity for 1 hour and 75% of capacity for a couple minutes for a Db check. Surprisingly quiet for a budget minded Generator/Inverter of this size 55.3 Db in Eco and 64.5 Db under high speed load. SO why only 3 stars? when I was researching options I found where the 4,000 watt unit had a oil drain tube installed (expected/assumed) the 5,500 would have the same...nope! Oil change procedure from the manual attached, Run engine until warm, remove oil fill cap, turn unit on side to drain oil...WTH! Not only will this be messy but it's extremely environmental unfriendly. If I had know this there's a good chance I would have selected a different MFG. Going to Harbor Freight and picking up a fluid transfer pump to change the oil.First power outage use proved this is the little Inverter that can. Supplied enough power to run two fridges, two freezers, multiple fans an lights and a Pit Boss 1600 pellet smoker.

 Used it on my RV, excellent!
